Type material. HOLOTYPE female. THE REPUBLIC OF THE PHILIPPINES: Mima Ropa, Region Oriental Mindoro, Baco , VI-2017, col. I. Lumawig ( UGAG) . PARATYPES. THE REPUBLIC OF THE PHILIPPINES: Mima Ropa, Region Oriental Mindoro, Baco , V-2017 (3 females), VI-2017 (3 females), VII-2017 (2 females), col. I. Lumawig, ( UGAG, UNAM) 8 females .

Description. Holotype female. Dorsal colouration. Head, pronotum, scutellum, clavus, corium, and abdominal segments III–VII black to dark brown; neck with two dark orange spots lateral to midline; antennal segment I black, II and III dark castaneous with basal joint yellow, IV dark yellow with basal and apical third black; anterolateral margins of pronotum dark castaneous; costal margin of corium pale castaneous orange; hemelytral membrane dirty white; connexival of abdominal segments III–VII dark reddish brown with anterior angle and posterior margin dirty yellow; connexival of abdominal segments VIII–IX dark reddish brown. Ventral colouration. Head, thorax and abdominal sterna black; labial segment I and II dirty yellow, III pale castaneous with basal joint dirty yellow, IV pale castaneous (some specimens with segments III and IV pale orange); coxae black; trochanters yellow; femora yellow, apical third reddish brown and surface densely covered with large reddish brown discoidal spots; tibiae yellow, basal joint reddish brown, and two inconspicuous pale castaneous rings, one near middle third, the other at distal third; tarsi with basal and middle tarsus yellow with apex castaneous, and distal tarsus reddish brown; anterior and posterior lobe of metathoracic peritreme dark yellow; pleural margins of abdominal sternites III–VII dark reddish brown with anterior margin and posterior margin yellow; genital plates black with upper margin of laterotergites VIII–IX dark reddish brown.

Structure. Head. Labium nearly reaching posterior margin of abdominal sternite III. Thorax. Pronotum with anterolateral margins clearly emarginate at anterior third; posterior lobe simple; anterior angles obtuse, rounded.

Scutellum. As long as wide. Hemelytra. Hemelytral membrane reduced to small flaps, reaching middle third of abdominal tergite III. Legs. Femora ventrally armed with two small subdistal spines and a few scattered along the surface. Genital plates. Laterotergite IX folded downward ( Fig. 14 View FIGURES 8–14 ).

Measurements (in mm). Female. Body length 12.29; head length 1.98; width across eyes 2.10; interocular distance 1.25; preocular distance 1.27; antennomeres length: I 1.80; II 2.52; III 2.02; IV 1.52; labial segments length: I 1.65; II 1.90; III 1.60; IV 1.60; pronotum total length 1.97; maximum width across humeral angles 2.65; scutellum length 1.25; scutellum width 1.25.

Male. Unknown.

Type locality. The Republic of the Philippines, Oriental Mindoro Province .

Etymology. The species epithet, stellata , is derived from the Latin noun stella, meaning star, and alludes to the pattern of spots on the femora.

Differential diagnosis. This unique species is clearly segregated by having the femora yellow, the apical third reddish brown, and the surface densely covered with reddish brown discoidal spots; tibiae yellow with basal joint reddish brown and with two inconspicuous pale castaneous rings, one near middle third, the other at distal third; labial segments I and II yellow; and the hemelytral membrane reduced as small flaps reaching middle third of abdominal segment III.
